Cameroon was a German colony on the west coast of Africa whose boundaries
had been agreed between Germany, Britain and France. Germany maintained a
powerful wireless station there to maintain contact with warships in the
South Atlantic.

Following the outbreak of war, an Anglo/French/Belgian
force of about 4,500 landed to attack Douala the capital. The Germans sank
ships in the river to form a barrier but this failed and Douala was
captured. They continued with the intention of capturing the entire colony.

Within a few weeks about 1,200 Germans had been captured but it took
until Feb-1915 to clear the Germans from all the townships and allied
control fully established.
